Stainless steel flat washers are mainly stamped from iron plates, generally in the shape of flat washers, with a hole in the middle. This kind of aperture specification is generally determined according to customer requirements. Such Stainless steel flat washers are usually thin sheets of various shapes to reduce friction, prevent leakage, isolate, prevent loosening or disperse pressure. This part can be used to achieve various similar functions in many materials and structures.
Process for processing Stainless steel flat washers: There are two main processes for flat pads, one is to remove burrs, and the other is surface protection treatment; after removing burrs, flat pads should be polished, vibrated or other methods to remove burrs and flashes .
Because threaded fasteners are limited by materials and processes, the bearing surfaces of bolts and other fasteners are not large, so in order to reduce the pressure on the pressure-bearing surface, washers are used to protect the surface of the connecting piece. Anti-loosening spring washers, multi-tooth lock washers, round nut stop washers, saddle-shaped, wave-shaped, and tapered elastic washers are used to prevent loosening of the connection pair.
The stainless steel flat washers ring is mainly used to reduce the pressure. When some parts are subjected to a large axial force, the washer is easy to be pressed into a dish shape. At this time, the material can be changed and the hardness can be improved. The locking effect of stainless steel gasket is general, and the important parts should be used as little as possible or not, and the self-locking structure is adopted. Suitable for high-speed fastening (pneumatic or electric) spring washers.
Stainless steel flat washers ring material: flat washers should be made of hot-rolled steel plates, pickled steel plates or cold-rolled steel plates after hot rolling, or punching of bars and pipes, as well as rolling, forging and other processing methods. The specific treatment method is determined by the manufacturer's choice.
It is better to use a gasket with a surface phosphate treatment to improve its anti-friction properties, otherwise it is easy to burn out or open the mouth due to friction and heat, or even damage the surface of the connected object. The structure of spring washer shall not be adopted at the joint of the plate. According to statistics, spring washers are less and less used in automobiles. Because of the large and uniform locking force, the coupling tooth shape in the American-made flat elastic pad tooth-shaped elastic washer is used more in the automobile industry, and the tooth-isolated type is less.
